The reports are haphazard, but after some legwork and a few minor bribes, the pattern becomes apparent. Several residents of the apartment complex reported home invations or robberies at various points over the course of the last two months. In all but one of the instances, the police had found no evidence of a break-in. Two other residents had reported to hospitals citing nocturnal headaches and insomnia. One other had had a brief stint in the same hospital as Mr. Villareal, claiming a stroke.
